not fit the outlet, have the proper outlet
installed by a qualified electrician.
3. Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
The conductor with insulation having an outer
surface that is green with or without yellow
stripes is the equipment-grounding conductor.
If repair or replacement of the electric cord or
plug is necessary, do not connect the equipment-
grounding conductor to a live terminal.
4. Check with a qualified electrician or service
personnel if the grounding instructions are
not completely understood, or if in doubt as
to whether the tool is properly grounded.
5. Use only 3-wire extension cords that

15. WARNING: Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities, contains chemicals
known [to the State of California] to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and cement or other
masonry products
• Arsenic and chromium from
chemically treated lumber
Your risk from these exposures varies,
depending on how often you do this type of work.
To reduce your exposure to these chemicals:
work in a well ventilated area, and
work with approved safety equipment, such
as those dust masks that are specially
designed to filter out microscopic particles.
(California Health & Safety Code § 25249.5, et seq.)
16. WARNING: Handling the cord on this product will
expose you to lead, a chemical known to the State
of California to cause cancer, and birth defects or
other reproductive harm. Wash hands after handling.
(California Health & Safety Code § 25249.5, et seq.)
17. The warnings, precautions, and instructions
discussed in this instruction manual cannot cover all
possible conditions and situations that may occur.
It must be understood by the operator that
common sense and caution are factors
which cannot be built into this product,
but must be supplied by the operator.
Vibration Safety
This tool vibrates during use. Repeated or
long-term exposure to vibration may cause
temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical check-ups
to ensure medical problems are not being caused
or worsened from use. Pregnant women or
people who have impaired blood circulation to
the hand, past hand injuries, nervous system
disorders, diabetes, or Raynaud’s Disease should
not use this tool. If you feel any medical or
physical symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Use tools with the lowest vibration when there
is a choice between different processes.
4. Include vibration-free periods each day of work.
5. Let the tool do the work.
6. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
